Fluorine refrigeration unit for for large vegetable cold storage
Sunicorn headquarter is located in Shenzhen city, production and R&D team is located in Shenzhen city and Kunming city in Yunnan province.Our main products include all kinds of vacuum cooler, cold storage room,ice maker etc.Company in the production of vacuum pro-cooling equipment, large cold storage, refrigeration equipment has been successfully applied in 12 provinces of China and other professional engaged in the preservation of circulation and food processing industry, a well-known enterprises, and has exported to Malaysia, Singapore, Thailand, the United States, Mexico, Eastern Europe and other places.And in the United States, California, Florida and other places set up a firm and after-sales service center. At any time to provide users with convenient and efficient technical advice, maintenance and domestic and foreign parts supply.
R22 belongs to a refrigerant restricted for use, with ODP=0.055 and GWP=1500. As required by Montreal Protocol, R22 will be weeded out gradually.R22 entered the freezing period in China in 2013. R22 has approximate performance to ammonia refrigerant.
The performance of R507 or R404a is not as good as that of R22,but the ODP of R507 and R404a is equal to 0,and the design pressure of the refrigeration system is slightly high.
The recommend sequence of refrigerants is R22,R507 and R404a from high overall system operation energy efficiency to low one.A fluorine pump feeding refrigeration system mainly includes refrigeration compressor unit,condenser,liquid receiver, low pressure circulation tank, refrigeration shield pump,end evaporator,etc. Auxiliary equipment including air separators, oil collector,etc. Shall be set up in the system.
Scope of Application:
Applicable terminal evaporator forms:all forms such as air coolers,coil,IQF machines,etc.;
Applicable to the case with drastic load fluctuation;
Applicable to the case where the feeding height or feeding resistance of the refrigerating circuit is large and the direct expansion feeding supercooling degree cannot meet requirements;
Applicable to the case where the end evaporator has no throttle valve installation space(the valve must be installed outside the storage and near the evaporator).
Without need to set up an active ammonia defense system;
Other advantages of the system are the same as those of the ammonia pump feeding refrigeration system.
The fluorine refrigerant charging volume is large,the price of refrigerant and refrigeration oil is high, the cost of the system is higher than that of the ammonia pump feeding refrigeration system;
Fluorine refrigerant is an environmentally restricted refrigerant for use and future system maintenance will be difficult;
The fluorine pump feeding refrigeration system shall be used with caution especially for the refrigeration system with the terminal being coils.
Cold Storage Room Instruction:
The modular cold room series is an integrated family of sandwich panels designed for quick cold room assembly. The panel configuration has been reduced to a minimum, so the overall effect is to offer the clients maximum design possibilities for cold rooms with a minimum amount of panels required on the site. All products from the modular range can be easily assembled without the need for special tools. Likewise they can be dismantled easily in order to move or enlarge them. The modular range has a wide variety of applications from general food storage to mortuary chambers.
Material of the Cold Room:
A. Panel: polyurethane insulation foamed by high pressure, density above 43kg/m3.
B. Economical panel thickness: 50mm,75mm, 100mm, 150mm for choice.
C. STeel sheet: Painted galvanized steel.
D. Door: Convex door, hinge door and sliding door available.
E. Compressor: Copeland, Bitzer.
